How Can I Process Data From "$this->request->getRawInput()" CodeIgniter4

Question

this is my ajax method that create a form data from an html table

$('#updateStudentInfoBtn').click(function(e){

// var delcare
let studentUUID = $('[name=studentUUID]').val();
let apiUrl = "/api/students/studentUUID";
var formObj = {
    firstname : $('[name="firstname"]').val(),
    middlename : $('[name="middlename"]').val(),
    lastname : $('[name="lastname"]').val(),
    gender : $('[name="gender"] option:selected').val(),
    dob : $('[name="dob"]').val(),
    admission_date : $('[name="admission_date"]').val(),
    admission_stage : $('[name="admission_stage"]').val(),
    current_stage : $('[name="current_stage"]').val(),
    current_section : $('[name="current_section"]').val(),
    name_of_guardian : $('[name="name_of_guardian"]').val(),
    relationship_to_student : $('[name="relationship_to_student"]').val(),
    occupation : $('[name="occupation"]').val(),
    phone_no : $('[name="phone_no"]').val(),
};

var form_data = new FormData();

for ( var key in formObj ) {
    form_data.append(key, formObj[key]);
}

$.ajax({
    method: "PUT",
    url: apiUrl,
    data: form_data,
    processData : false,
    contentType : false,
    cache: false,
    success: function(res){
        response = JSON.stringify(res);
        if(response.status == 201) {
            // show success alert
        }

        //location.href="/admin/allstudents";
    },
    error: function(err){
        console.log(err);
    }
});

});

and this is my php script to retrieve the data sent over put method; have omitted the class part.

public function update($studentUuid = null)
{
    $studentModel = new StudentModel();
    $studentData = $studentModel->where('uuid',  $studentUuid)->first();

    $input = $this->request->getRawInput();
    return print_r($input);
}

the result of print_r give me this text i dont know how to process the data ::

Answer 1

for testing use postman so donwload it

second if json request set request postman to put

but if formDAta reqeust set request post then add this filed to form data value

var form_data = new FormData();

//this works for you
    form_data.append('_method', 'PUT');

for ( var key in formObj ) {
    form_data.append(key, formObj[key]);
}
 form_data.append('_method', 'PUT');


$.ajax({
    method: "POST",
    url: apiUrl,
    data: form_data,
    processData : false,
    contentType : false,
    cache: false,
    success: function(res){
        response = JSON.stringify(res);
        if(response.status == 201) {
            // show success alert
        }

        //location.href="/admin/allstudents";
    },
    error: function(err){
        console.log(err);
    }
});
